Following the news that Roger Federer and his wife Mirka have had another set of twins, this time boys, leading bookmaker Coral is offering 50-1 for any of his children to win a Grand slam title in the future.

Federer's twin daughters Myla Rose and Charlene Riva are 250-1 to win the ladies' doubles championship at Wimbledon, while newborn twins Leo and Lenny are 200-1 to achieve success in the Wimbledon men's doubles.

"If both twins follow in their father's footsteps, there could be a Federer domination at Wimbledon in the distant future, therefore the odds on one of his children winning a major at 50-1 could be very generous," said Coral's John Hill.
